SHOCK ABSRBER.

Application led February 23, 1921. Serial No.. fl-7,982.

To all milf/m it' Way concern.'

i or-n that nur (liessen, a citizen oi the United States7 residing` at ihann'oelr, in the oountj,7 oi Creel? and `State olr Oklahoma, h are i rented certein new and useful lmproremei s in Shock bsorbers, of which the ollowing` is a specicetion.

rlhis invention relates to shook` absorbers and has :tor its object 'die production of suit` able means 'tor (reacting with the springs oil" vehicles to prevent the effect of the rebound oi" the relucie, or e portion tbereot., when the spring* has been materially str-aine: and also to increase he resilient ei'lect ot the spring-js ol the vehicle.

@it the aceompanyinpv drawings Fie. 1 is an eleration ot a shoelr absoriier associated with the spring oiv the vehicle, which embodies the features oi my invention; Fie'. 2

is a perspective View ol one element ot the shook absorber.

lt is common in case oit vehicles, particularl).y automobiles to provide some means flor reducing the shock oit the rebound or". the vehicle when a sudden material jar causes the springs to be materially strained and. then to sp1 the body ot the vehicle itself. One form off" shoe r ebsorber used 'tor this purpose is illustrated in `1 und comprises a compression snrino 5i which is Jositioned between a L lj i plate (l fiXedto the outer end ot a lever is pivoted, by the pivot 10. to a braclret l1 which is fixed to some portion oli the traine oth the vehicle such as the brake housing' 12 which in turn is fixed to the asile 13. The sining 111- mayT be one .oil the main transverse springs ot' the vehicle. in the rear or the front as the case may be; and ithas its end 15 pivoted` by means oit a bolt 16i to a. han-` Qjer 17., which is in turn piroted by a pin 187 to the lever .1. The base 9, supporting the plate 8 o t the low-er end ot the compression. pin 5, is slidably mounted on the spring' 14 by means of pairs of lugs 19 projecting from the base 9, on each side et thel spring` 14, and having bolts 2O connecting the lower ends ott each pair of lugs.

It is common with such shook absorbers to depend upon the lugs 19 and the bolts 20 to maintain substantially in place the base 9,

with one oY nne' backwardly carrying with it and a plate 9 fixed to a base 9. The lei/'er 7T an arm e spring lil l provide es which connects the bolt ie bolts 20, and thereby at all `times prevents the abnormal displacement of the base 9. A

ln operation the erin 7 is limited in its ting' upward movement by a stop 22. lto the bracket ll; and in case ot the tenoeizoy ot the vehicle or an); portion thereolflio be forced upwardh7 by the rebound of the spring l-lthe arm 'T'is held trom haeltrmrd movement by the stop and the resulting Compression of the spring' 5 gradually stops the upward moif'ement ot the 'Vehicle, thus overcoming the strain on the Vehicle due to the ordinary method. ci' stop` pine' the upward moi/'ement ot the Vehicle. Bj: the use ou the link 2l the distance between the base 9 en d the end 15 of the spring` always maintained such as to produce the best result with the spring 5, keeping its in line with the axis oiE both plates 6 and 8; whileA otherwise more less creepo'li the base 9 would result. and such an almornial displacement. the base would nenes .tate a readjustment thereoi. Also the bese i'nay be slidably mounted on the springp 1.4-, so' thingy as' the sprin Changes torni. the base slide treely thereon to accommodate the spring 5.

l Claim as my invention:

A vehicle spring and. a shock absorber therefony said obs. :ber oomprisino` a baseplato slidabl;Y .mounted on and above the springn lugs preiectingz` trom said plate and ei:tendine on each side oit and below said spring, the lower end oit each ot said .lugs hei/'ing' opening` therethrough below said spring'.y bolt j iassine; through said opening'. arranged to be pivoted to the frame ot the vehicle, n con'ipression spring; positioned between the free end of said arm and seid, bose-plate, and a hanger pivoted to said J.on a linlr i" tl arm and to oneend of said spring; in comln testimony whereof, l hereunto set my hand.
